BACKGROUND

Barriers, such as window blinds, such as venetian blinds, and verticalblinds, screens, shields, etc. may be used in residential and commercialapplications as window coverings, screens, barriers, etc. to act as aphysical barrier, and because of their ability to selectively vary theamount of light passing through a window, glass door, skylight, or thelike, by the varying deployment, or adjustment of a plurality of vanes,louvers or slats.

Current anti-ballastic protection systems in residential and commercialapplications such as armored doors, shutters, and windows are usuallymade of metal or a material containing at least one metal plate, andthus having an extremely high weight. Some plastic systems exist thathave lower weight, but that are very flimsy and weak, and thus wouldprovide no protection from projectiles or other forced entry into thedwelling.

It would be useful to utilize the widespread use of various types ofbarriers to provide unauthorized entry protection to individuals andorganizations in residential, commercial, government, federal buildingand mobile or any suitable application.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

This application includes modifications and additional alternatives tothe bullet proof blinds disclosed in U.S. patent application Ser. No.14/476,206 filed on Sep. 3, 2014, and U.S. patent application Ser. No.15/050,639 filed on Feb. 23, 2016, both incorporated herein by referenceand substantially reproduced herein below.

This application includes modifications and additional alternatives tothe bullet proof blinds disclosed in U.S. patent application Ser. No.16/215,162, filed on Dec. 10, 2018, and incorporated herein by referenceand substantially reproduced herein below.

There are various proposals for improving ballistic protection ofindividuals and interior spaces in buildings and vehicles as discussedin the related patent applications listed at the top of thisapplication. The inventor has discovered that a problem with manycurrent solutions to these problems is that the protection devices don'tabsorb much of the energy that is contained in the ballisticprojectiles, such as shrapnel or bullets that have been fired. Theinventor has determined that one solution to this problem is to allowthe protective device, such as a screen, panel, shroud, blind, or otherbarrier to hang freely, perhaps in a weighted manner, which allows thebarrier to flex, vibrate, flow, sway and otherwise move in response toreceiving the projectile, thereby dissipating some of the energy fromthe projectile that otherwise would remain as kinetic energy. Thisreduces the amount of damage and potential penetration of the projectivewith respect to a given amount of projection.

As shown in U.S. patent application Ser. No. 16/215,162 and its relatedparents, all incorporated herein by reference, various deployablebarriers using non-metallic anti-ballistic materials can be formed foruse as window blinds and similar barriers that might be provided atvarious locations in buildings. Use in windows, doorways, hallways, andother interior locations as a deployable barrier that is stowed when notneeded provides a way to protect various interior spaces withinbuildings. Furthermore, barriers can be provided within vehicles ineither deployable or fixed manners (or both). Deployable barriers mightbe used to protect vehicle windows, doorways, hatches, and other accesspoints, whereas permanently deployed barriers could be provided withinvehicle voids such as in doors, body panels, and other locations.

Of particular interest for at least some embodiments are barriers thatare not fixed on their sides and bottoms, but that may include weightsto increase their overall mass. Such barriers are free to flex and movein response to receiving a ballistic projectile, thereby converting atleast a portion of the kinetic energy of the projectile into kinetic andheat energy in the barrier distributed across the entire surface area ofthe barrier. Allowing this free motion actually increases theeffectiveness of the barrier by reducing the penetration energy of theprojectile, thereby effectively improving the ability of the barrier toprotect the desired person and/or interior region.

Of additional interest for at least some other embodiments are barriersthat are still designed to flex and move in interior portions, but thatare fixed on their sides and/or bottoms (i.e., fixed around a perimeteror portion thereof) in order to add additional stability and strength,such as to prevent a person or large object from entering a protectedregion. Such barriers are still free to flex and move in response toreceiving a ballistic projectile in at least portion of their surfacearea, thereby converting at least a portion of the kinetic energy of theprojectile into kinetic and heat energy in the barrier distributedacross the entire surface area of the barrier. However, along with afixed top, the fixed sides and/or bottom prevent individuals or objectsfrom bypassing or pushing aside the barrier to get into the protectedregion. Hence, only the perimeter, or a portion of the perimeter, isfixed and secured, whereas an interior portion of the barrier is free toflex, vibrate, and otherwise kinetically absorb the energy of aballistic projectile impinging on the barrier.

FIG. 1 shows a schematic of a basic general barrier design 100 that canbe used for many of these various barriers. The primary protective partis a barrier layer 110 which in many of the example embodiments will becomprised of a laminate of a plurality of layers of flexibleantiballistic material. FIG. 2 shows an example of such a laminate 400that can be used, with an inner layer 420 that is also likely to be alaminate, and with optional outer layers 410 and 430 providingprotection and/or decorative layers.

The inner layer 420 can be comprised of a plurality of layers ofanti-ballistic material that might include layers including one or moreof: plastic, composites, wood, metal, fabric, fiberglass or any othersuitable anti-ballistic material including, but not limited to, Kevlar®(which is a synthetic fiber of high tensile strength comprised ofpoly-para-phenylene terephthalamide) or Lexan® (which is a transparentpolycarbonate of high impact strength) or Lucite® (which is a solidtransparent plastic comprised of polymethyl methacrylate) or DuPont™Tensylon® (which is an ultrahigh molecular weight polyethyleneanti-ballistic material), or a boron treated cloth, or a plexiglass withanti-ballistic properties, for example, or any combination thereof.Anti-ballistic gel materials such as shear thickening fluids that may betransparent can be used to saturate a material or fill voids (some ofthese materials harden upon impact and might be comprised ofnon-Newtonian fluids that that thicken in response to force). Othermaterials or combinations described elsewhere in this document can alsobe used as an alternative or supplement these materials.

All of the layers provided in the laminate 400 (that may be used as thebarrier layer 100 of FIG. 1) can be secured together using anycombination of a number of securing approaches, including the use ofglue, heat bonding, stitching, quilting, or other means, or anycombination thereof, to secure the various layers of the laminatetogether. Hence, the laminate can be manufactured using stitch bonder orquilting machines, leading to a multi-layered laminate having aplurality of flexible layers and leading to a flexible laminate. Notethat each layer might be comprised of thin, solid sheets of any ofanti-ballistic material or the material could be woven into a durableand tough and flexible fabric using threads and/or fibers of thematerial.

An aspect of the first surface that the bullet hits can be designed toact like a strike face, to slowdown and deform/mushroom the bulletbefore it hits the inside layers which then stop the projectile. Forexample, the outside layer can be anodized, coated, plated ortreated/coated to provide the first task of slowing and deforming thebullet before it hits the layers that do the heavy lifting.

The outside strike face can have ridges or protrusions to roll thebullet. There could also be a ceramic veneer or layer to act as thestrike face. The strike face layer can also be a combination ofdifferent technologies such as coating a ceramic veneer, such as to keepthe weight down.

The whole barrier assembly can be spring loaded or partial break away todissipate energy, or to move in an X, Y or Z direction. The strike facescould slide in pockets of the barrier. The hinges can be metal orcomposite based.

A security film can be applied to the strike face to slow down andmushroom the projectile such as a bullet. The material would not beflammable like glass and other methods currently used, would be saferfor schools etc. On lightweight metal barriers or blinds (having metalslats) a coating or layer/foam, or lightweight material slides in to theextrusion or stamping.

The barrier shape can be used to change the roll of the bullet, variousangles to get bullet on its side, for example. The point of the first,outer layer (other than surface decorative layer(s)) is to act as astrike face and slow down and mushroom flatten out thebullet/projectile. When glass is in front of the barrier, a securityfilm can be applied to a surface of the glass that acts as a strike faceto slow down the bullet.

On light weight metal barriers (e.g., shutters or blinds) a coating orlayer of lightweight material such as Tensylon that fastens or slidesinto the extrusion or stamping. The barriers could also be a clear lexanthat darkens with sunlight. The barriers or shutters could also be alaminated/sage glass that darkens automatically or when electricity isapplied.

Barriers can also be a shutter made of tensylon that has a metal,ceramic or wood veneer surface, to make that barriers more presentablebut also act as a strike face. The slats or edges can also have a metaledge to improve the appearance. Lightweight materials light dyneema canact as a ladder or to keep the barriers aligned. A metal shutter can bea extrusion or stamping that the cavity is filled with a combination ofmaterials foam, coating, kevlar polyurethane, or anti-ballistic gel,depending on the function of providing strength, sound dampening, strikeface, decorative, etc. The fabric laminate may also be coated withvarious substances to help provide decorative features, or to stiffenouter layers to deform bullets, or to provide sound deadening, orotherwise provide other desirable features.

The barriers can be provided in modular sections that can deployhorizontally or vertically. The device can deploy from the top bottom orside. Sections can be provided in fabric or hinged, daisey chained, orwired together. Speakers and/or lights can be provided in various sizes.

The sections can be electrostatic or the equivalent of a thin speaker toblock light sound bullet etc. (as described in more detail below). Thebarriers can provide light or emitted sound. Barriers, such as blinds orshutters can use speakers for security, and can block light and providesound. Speakers can be provided to vibrate the barriers do active noisecancellation.

Barriers can be designed in a way to dissapate the energy from the shotthrough motion, destruction, heat dissipation, deformation, or otherprocesses. They may sacrifice themselves much like a formula one carsacrifices itself to save the driver.

A cavity or pockets of the barriers (e.g., blinds or shutters) can beprovided to house different modules according to the needs desired or acombination of elements. Slats could rotate on there axis to displaceenergy or change side according to purpose.

The barriers can be comprised of various layers of fabric material. Thematerial layers may be secured to each other by stitching, quilting,gluing, welding, or merely the edges may be bound and perhaps tacked ina few spots leaving inner layers unsecured to each other, allowingmotion or pockets for other uses, such as inserting materials or gels.Perhaps not stitch bonding or perhaps a very open quilt pattern.

A logo can be provided, such as using 1 inch or ¾ inch binding, or bysewing in a logo. As many as 18 plies or more of woven Kevlar fabric orother material can be used in the laminated material. Depending on theweave and year size, the result can meet at least a level IIIaprotection, or more. Fabric style can be 600d Kevlar KM2 Plus, 24×24square yarns per inch, plain weave construction, Polyester stitchingyarn, 75 denier textured yarn. Stitch pattern can be: linear chainstitch (machine direction), 3.5 gage spacing. Quilting can be used tosecure the layers to each other. Layers secured only at the ends canalso be utilized. It is noted that the very looseness, flexibility, andmotion of the material aids in energy absorption, providing betterballistic protection and penetration avoidance.

Referring back to FIG. 1, the barrier layer 110 will be fixed at one ormore ends using either or both top mounting structure 120 and sidemounting structures 140 to securely connect to the structure 150 of thebuilding or vehicle. These structures will securely fix one end of thebarrier layer 110 to a secure structure, such as a window or door frame,a ceiling, or vehicle panel or frame. Note that where the barrier is ofa deployable embodiment, the top mounting structure 120 may includefeatures that retract and/or store the barrier layer 110, such asdisclosed in a number of the parent applications in embodiments such asdeployable window blinds.

In this generic approach, as discussed above, the barrier layer 110 willbe a flexible layer that can move, vibrate, swing, and otherwise convertthe kinetic energy of the ballistic projectile into kinetic and/or heatenergy in the barrier 100 by nature of having barrier sides 112 and abarrier bottom 114 that are not secured to any structure in this freehanging embodiment. A weighted end 130 can be provided on the barrierlayer 110 to add mass to the barrier so that the kinetic energy of theprojective is also transferred to this mass as kinetic energy by movingthe mass of the end 130, which can include lifting the end, swinging theend, and other types of motion. The end 130 also helps keep the barrier100 in place by providing stability and in a deployable embodiment, mayalso help deploy the barrier 100 in emergency situations, as is alsodiscussed in the parent applications.

As an alternative, the side mounting structures 140 may be extendedfurther, even along the entire length of the barrier sides 112, tosecure the sides. Furthermore, an optional floor structure 152 can beprovided at a bottom of the barrier 100, such as on or beneath a floor,to secure the barrier bottom 114 when deployed. For example, bottom 114may include a magnet along it's length as part of the weight 130, andthe floor structure 152 could include a magnet of an opposite pole(which may be an electromagnet), to secure the bottom 114 to the floor.Alternatively, floor structure 152 might include a latch or grippingdevice that secures the bottom 114 to the floor. Hence, in conjunction,extended side mounting structures 140 and/or the floor structure 152secures the barrier 100, when deployed, to prevent individuals orobjects from passing beyond the barrier 100 into a protected region.

Note that automatic deployment, based on the detection of a dangeroussituation such as an explosion or gunshot (e.g., triggered by soundwaves, breaking glass, light flash, or even detection of intruders, forexample) can be provided as discussed in the parent applications. Manualdeployment through activation of a motor or drop function through use ofa switch, lever, or other manual activator can also be provided as analternative or supplemental means of deployment. The weight 130, whenprovided, can aid in quick deployment. Such barriers can be provided inwindows, doorways, hallways, or even across rooms, for example.

Alternative approaches where the barrier is installed in a rising mannercould also be provided. For example, posts may rise out of the ground orfloor for deploying the barrier from the ground up, with the topportions free to move, or with sufficient flex in the barrier to allowfreedom of motion. Such devices can protect hallways, stages, rooms,doorways, garage doors, or other locations in and out of buildings.

FIG. 3 shows a particular embodiment of a generic approach by providinga blind 305 with support and stowing structures 320, 315 for deployingthe barrier layer 310 with weight 325 in a window or door frame.

Referring to FIG. 2A, an example embodiment of a barrier system, such asa window blind system, is shown. The blind system 5 includes a pluralityof members such as slats, (also called louvers or vanes) 10 resting orhanging on the rungs of one or more ladders 15, which are movablysuspended from a head, bottom or side rail 20, which may be mounted to awindow or door frame. The slats 10 could be of horizontal or verticalorientation.

The slats could be formed having matching grooves or a tongue and groovesystem to allow the slats to interlock or overlap with each other in amore secure way to ensure better resistance to ballistic intrusion, asdescribed elsewhere herein. For example, the slats might overlap by ½inch.

The slats 10 can be of conventional construction but with updatedmaterials, and can be constructed of a number of different materialshaving desirable properties, including, but not limited to, thefollowing materials: plastic, composites, wood, metal, fabric,fiberglass or any other suitable anti-ballistic material including, butnot limited to, Kevlar® (which is a synthetic fiber of high tensilestrength comprised of poly-para-phenylene terephthalamide) or Lexan®(which is a transparent polycarbonate of high impact strength) orLucite® (which is a solid transparent plastic comprised of polymethylmethacrylate) or DuPont™ Tensylon® (which is an ultrahigh molecularweight polyethylene anti-ballistic material), or a plexiglass withanti-ballistic properties, for example, or any combination thereof.Other materials or combinations described elsewhere in this document canalso be used as an alternative or supplement these materials.

In an example embodiment, the slats could be provided as a laminate,such as steel or aluminum with a carbon fiber or tensylon or fiber glassbacking. Decorative layers or paints can be provided for room esthetics.Also, fabric can be treated with boron to form a ballistic resistantmaterial. For example, a fabric can be dipped into a boron solution,then heated in an oven at more than 1000° C., which changes cottonfibers in the fabric into carbon fibers, such that the carbon fibersreact with the boron solution to produce boron carbide.

The slats 10 could vary in shape, width, thickness, and/or orientationto form blinds of various styles and construction, as desired. The slats10 can be made flat or curved across their transverse dimension, theycan be of any desired width or length or thickness, and they could beprovided of different dimensions, such as, for example one, two, three,or four inches wide or any other suitable width for the desiredapplication. Rather than horizontal slats, the slats may be arrangedvertically, as shown elsewhere in this document. The lengths of theslats for the various blind designs can be varied according to thewindow or door size that they are being utilized to protect, and theycould be of a length of a foot or more, up to 4 to 8 feet or more, asdesired.

FIG. 2C, shows an arrangement of vertical blinds having a valance 52 andvertical slats 54, shown with the slats partially retracted. Forvertical blinds, a rail 56 can be provided at the base of the blinds toprovide further structural strength to the slats via connector 58, whichcomprise a tab or other structure that is inserted into a slot in therail 56 to avoid deformation of the slats 54 during a protectivefunction.

Turning to the operation of the blind system 5, the slats 10 can betilted (e.g. by rotation) by a tilt mechanism 50 to let in partiallight, such as when a tilt wand or cord 25 is used to adjust the slats10. The slats 10 can also be lifted or collapsed by a lift mechanism 100(for example, to fold or accordion the slats into a compact position) tolet in full or nearly full light, for example.

Referring to the example embodiment of FIG. 2B, the slats 10 aresuspended by the ladder 15 which is comprised of at least two strips ofcloth or string or tape 30 that allows the slats 10 to be suspended in amanner such that all slats 10 in unison can be rotated nearly 180degrees, such as to go from an open condition (state) to a closed(protective) condition (state). The tape 30 can be made of any flexiblematerial such as fabric, plastic, nylon, polyester, or any flexiblematerial or the like. The ladder 15 further comprises a connector tape35 which connect the two strips of tape 30 together. Rotating thetilt-cord 25 causes the slats 10 to rotate/tilt a longitudinal axis inorder to open or close visual access to the outside from inside the roomin which the blinds are installed.

As an alternative to rotation, in some embodiments the slats may beopened and closed by sliding the slats or collapsing the slats together,for example. And the entire blind may be retracted toward the top(valence) structure or deployed as desired.

The slats 10 of the blind system 5 further comprise rods 45 routedthrough rod holes 40. In this example embodiment, each slat 10 comprisesat least one rod hole 40. At least one steel rod 45 which is affixed tothe head or bottom rail 20 runs through each slat 10. The slats 10 couldpivot about the steel rod 45 which is encased in the slats 10. Pullingthe lift-cord activates the lift mechanism 100 causing either the bottomrail or the top rail to rise, sequentially collecting the slats from thebottom up or the top down and compressing the entire array of slats 10against the top-rail.

Turning to FIG. 3, the blind system 5 may include a rotator member, ortube 60 provided for rotation of the rotator 60 within an axis providedin the head box valance 70. The tilt cord 25 is fixedly attached to therotator 60 and hangs downwardly from the head box.

In an example embodiment, the slats 10 may have a groove 65 and and/ortongue 68 that may run the length of the slats 10 to interlock the slatstogether during deployment. While the embodiment shows the groove runsthe length of the slat, it is appreciated that a groove-tongue systemlocated at the edge of the slat 10 may suffice. The groove 65 and tongue68 allows slats 10 to interlock when they are in a closed position foradditional strength. In another example embodiment, the slats 10 canhave fasteners that allow them interlock for additional strength. Thefasteners could engage with the window or door sill for added strength,if desired. Or magnets or electromagnets might be used to interlock theindividual slats together. Another example of such a tongue-and-grooveinterlocking approach is shown in FIG. 9A, described below.

FIG. 4. Illustrates an example of a control system which may be used byany of the embodiments described herein to control the blind system 5.The control system can include a controller 202 with one or more sensorsthat form a sensor array 204 connected to the controller 202, and apanic switch 206 connected to the controller 202. The sensors may bepre-existing sensors in a home defense system or conventionalafter-market sensors capable of detecting ballistic signals such assound (e.g., gun shots or breaking glass), gun powder, gun impact,muzzle flash, temperature, and the like. The sensors could be any ofthose typically used to detect a break in, for example. The controller202 is connected to a user interface 210 whereby a user may activate andapply settings to the blind system. The controller 202 is also connectedto a motor system 208 for actuating the blind system upon receivinginformation indicating that a threat is present and that the blindsshould be closed (i.e., put into a protective state such as a ballisticprotection mode).

Where a building may already have a central control system (e.g., asecurity or other alarm system), controller 202 may utilize such asystem by adding additional customized code for operating the blindssystem 5. In another example, the blinds could also utilize groundsourced radar, infrared (heat), sonar, or some other active or passivedetection system. The sensor array 204 can include one or more heatsensors, infrared sensors, video sensors, audio sensors, smokedetectors, or other types of sensors, or may utilize already existingsensors of a fire or burglar system, for example. Any of the sensors inthe sensor array 204, the panic switch 206 or the user interface 210, orany combination of these components, may be connected to the controller202 in a wireless manner, such as by WiFi or Bluetooth, for example, andthe panic switch and/or user interface could be implemented on a cellphone or tablet computer, for example.

The system or any of its components may be controlled by any external orinternal system, such as one that may exist prior to the installation ofthe blinds. For example, the blind system could be tied to an externalsystem such as an alarm system or video cameras with analytics. Theblind system could also be controlled remotely via the internet or aWiFi or Bluetooth connection by any connected device such as a tablet,computer, PDA, or a smartphone. Blinds such as disclosed herein would bevery useful in a panic situation in a school or federal building. Suchblinds could also be used in a lock down situation to prevent people orvaluables from leaving the premises, for example. FIG. 9, describedbelow, shows an example embodiment of a remotely controllable system.

The blinds could be retrofitted to an existing building or otherstructure, and adapted to tap into existing security or burglar alarmsystems, for example, or they could be added during structureconstruction.

The blinds could also be adapted to sense the location of the occupantsof the building and close by according to predetermined parameters suchas direction of threat and the location inside the building that wouldbe the best to return fire from. Blinds could also be controlled byfacial recognition, video analytics, or by the occupants' voice or anyother suitable biometrics, such as for recognizing an threateningperson, such as an ex-spouse, or ex-employee who has made threats oracted in a threatening manner, or otherwise recognizing a wantedcriminal or an enemy soldier, for example. When the blind system 5 isactivated, the slats 10 may be configured to overlap each other to formthe interlocking pattern discussed above so as deflect bullets, shells,or other ballistic weapons to prevent a fatal impact and/or propertydamage. Such blinds can protect from thrown objects as well, such asrocks, grenades, bricks, molotov cocktails, etc. Blinds could becontrolled individually or together with a timing mechanism.

The blinds could be configured to protect against remote monitoring ofsound and conversation, such as by providing random vibrations to theblind to avoid vibration detection by remote monitoring devices, forexample.

As an example use, the blind system may be provided in an open statewhere the blinds are provided in an open condition (e.g., with openslats) to allow viewing through the blinds, or the blinds in a retractedposition. The blind system sensor array would detect a potentialintruder or the sound of gunfire using visual, auditory, or other sensedinformation. The system would then automatically enter a protectivestate, such as by closing the blinds (e.g., closing the slats) ordeploying the blind (by lowering it to cover the window), or both, toprotect the interior of the room from external entry of projectiles(e.g., bullets), for example. Or the system may detect the entry of aballistic projectile (e.g., a bullet, rock, etc.), or threatening shoutsor yells, sirens, explosions, proximity of threatening individuals,etc., in which case the blinds would be activated into a protectivemode.

In an alternate example embodiment illustrated in FIG. 5, the blindsystem 105 can reside between two glass panes, such as safety glasspanes 135 for use in applications like automobiles, airplanes, boats orother mobile applications. The blind system 135 may also be used instationary applications like residential and commercial applications.The safety glass panes can be made of any lightweight glass materialwhich is useful in an armored car to reduce weight of the glass usedwhich improves the fuel efficiency of the vehicle.

In an example embodiment, the slats 110 used between the safety glasspanes 135 could be comprised of a composite or laminate, such as fabricwith a carbon fiber or tensylon or fiber glass backing or otherballistic resilient backing.

In an example embodiment, the glass panes 135 could have a layer ofsafety film 140 such as, for example, Cellulose acetate film, 3M safetyfilm, Armor guard films or the like for additional protection. Thesafety film can be between 4 mil to 10 mil, for example, although otherthicknesses could be used. In another example embodiment, the glasspanes 135 could be made of fire glass with a gel center such asmanufactured by SAFTI First, for example.

In an automobile application, the blind system 105 could be controlledwith safety in mind so that a driver does not lose all drivability atonce and improving the ability to evade. For example, the blinds couldhave a small port hole for the driver of the vehicle to see out of toallow the driver to continue to drive toward a safer area, for example.Or the blinds could be comprised of a transparent material withanti-ballistic properties, or a material with anti-ballistic materialswoven therein.

In use for mobile applications, such as in boats, or airplanes orautomobile, the blind system 105 could be configured to tilt or closethe blinds based on temperature, sound, threat, geographic terrain,environmental conditions and any outer suitable factors. For example, asa vehicle goes up a hill, the blinds can be adapted to tilt so that airor light can get in and not bullets.

The blind system 105 could also be fire rated to prevent fire fromspreading to the next room or structure through the use of fireretardant or preventive materials, where the blinds can be automaticallyclosed when a fire is detected through monitoring of temperature, light,or infrared, for example.

In another example embodiment illustrated in FIG. 6, the blind system305 may have a roll up blind (e.g., window shade) configuration that mayutilize an anti-ballistic fabric material 310, for example, and that canbe used as protective covering to protect equipment such as, forexample, a radiator, or a ventilation system, or on an intake area of ajet engine, engine, window, radiator, or gas tank of an automobile (orother vehicle), or any other suitable protective covering applications.The roll-up blind system 305 may be made of bullet resistant fabric suchas Kevlar or Lexan or DuPont™ Tensylon®. Other materials describedherein could also be used, as an alternative or to supplement thesematerials. In such a system, the blind may be comprised of a contiguoussheet of material, or patches of such material, rather than slats.

In an alternate example embodiment to the slat blind system, the roll upblind system 305 can reside between two glass panes, such as safetyglass panes 135 for use in applications like automobiles, airplanes,boats or other mobile applications, as shown in FIG. 5 or FIG. 8. Such asystem might utilize a Kevlar curtain that falls between windows panes,or even in front or behind a single pane.

Any of the protective blinds described herein might also be stored in aceiling rather than a valance structure, and in some cases bullet proofpanels rather than blinds might be used, where deployment in emergencysituations means that the blinds drop from the ceiling to provideballistic protection.

The fabric blind 310 could also tilt or otherwise be operated accordingto the threat or terrain. The fabric blind 310 could close from the topor bottom depending on the design of the building or application. Thefabric blind 310 could also run left to right, for example. The blindscould also tilt according to the threat or terrain. For example withvehicle application when the blind is used as a radiator cover, as thevehicle goes up a hill the radiator blinds tilt so air can get in andnot bullets.

In an alternate example embodiment, the roll up blind system 305 may beused for windows, doors, entryways, or any other desired application ina building or vehicle. The roll up blind system 305 could suspend from arail 315 and that may be disposed within a head box 320 (acting inconcert at a valence) and may be weighed down by bottom rail 325 tomaintain its position and add structural strength. The weight of thebottom rail can vary to match the desired application, or it may bepaired with a structure enhancement such as through the use ofelectromagnets or a structure secured to a sill or floor. A reel cord330 may be used to be roll up the blinds 310 or to roll down the blind310. The reel cord 330 may also be pneumatically or automaticallydriven, such as by using a chain. The lengths of the blind 310 can bevaried according to the window or door size that they are being utilizedto protect, and they could be of a length for the desired application.

Generally, any of the blind systems provided herein will typically beprovided with blinds that can be placed in an open state at the requestof a user to enable viewing through the blinds, and/or to allow forairflow and/or light flow and/or other flow through the blinds. Suchblinds can also be closed at the request of a user, in which case theblinds may also be in a protective state. The blinds can also beprovided in an intermediate state, able to both provide some limitedballistic protection and to let in a substantial amount of light. Upondetection of a threatening condition, such as detection of a gunshot ora flying projectile, or by activation of a panic button or securitysystem, blinds that are in an open state will be transitioned into aclosed, protective state to protect against ballistic projectiles orother threatening materials.

In addition to the embodiments disclosed in the '206 application anddescribed above, various forms of vertical blinds based on conceptsprovided in that application are also provided. Additional materials arealso disclosed for constructing the blinds in this and that application.

The use of a Kevlar fabric having expanding baffles between the layersis one alternative in such blinds. By providing baffles in the material,the material is enabled to expand in an outward direction, which willhelp to absorb some of the energy provided by a ballistic impact.

The fabric blinds could utilize horizontal or vertical pleats or slats.Separate vanes or material can be provided to add bullet prooffunctionality, such that existing blind designs, that may haveornamental aspects, can be supported by a set of bullet proof blindsplaced underneath the current blind design. The blinds would act inconjunction to open and close in a traditional manner, with the addedfunctionality of providing ballistic projectile protection. Solenoids ormotors, or electromagnets, or other electrical or mechanical devices canbe used to mechanically open and close the blinds.

In some options, a bullet proof blind (that may be provided behind or infront of a traditional blind or a as a full replacement) may remainnormally in a retracted or otherwise open mode. The bullet proof portionof the blind may be hidden in a valence of the blinds, for example, orbe rotated or retracted in an open position. The bullet proof materialcan be automatically deployed, such that upon a triggering event (suchas the detection of a gunshot, or the triggering of a proximity alarm orother type of burglar alarm, for example) the bullet proof (ballistic)blind would then deploy, such as by dropping into place from a valanceor roof or ceiling, for example.

Such a dropping ballistic blind might be comprised of panels or slats ofballistic material that are folded, overlapped, or otherwise collapsedin the retracted position, or it may comprise a roll of ballistic fabricthat rolls to retract, and unrolls to deploy to form a ballistic layerof protection. A weight may be provided at the bottom of the roll to aiddeployment (e.g., unrolling) and to help keep the material in place forstopping or slowing the projectiles. Alternatively, some structure toincrease the strength of the deployed blind could be used, such aselectromagnets or electrical or mechanical latches at the base to securethe deployed blind to the floor or window sill or wall or otherstructure.

The blinds can be placed between layers of glass, for example, which canbe used in original installations or to retrofit existing windows. Theblinds may be used in conjunction with bullet proof or bullet resistantglass. For example, blinds such as disclosed in U.S. Pat. Nos. 5,826,338& 6,070,638, incorporated herein by reference, could be modified usingthe materials disclosed herein to add ballistic protection to suchblinds. Automatic deployment functions, as also described herein, couldalso be provided.

FIG. 8 shows an example of ballistic blinds provided between panes ofglass, including slats 520 connected by center post 530 provided betweena first pane 501 and a second pane 505 of glass, with a bottom 540 and avalence 510 which may store the blinds in a stowed position and maincontain a mechanism to automatically drop the blinds upon detection of aballistic event. Alternatively, the blinds may be permanently deployedbut the slats rotated automatically or manually.

In particular, vertical blinds (or shades) can be used to providebullet-proof protection, as described herein. Such blinds, although theymay use hanging panels, can still provide ballistic projectiveprotection by absorbing energy from a bullet or other projectile. Such adevice may be comprised of a plurality of panels made of a ballisticmaterial. Acceptable materials may include a high-density polymer (e.g.,polyethylene, Tensylon), ceramic, metal (e.g., steel, titanium, andalloys thereof), aramid fiber (e.g., Kevlar), polycarbonate (e.g.,Lexan), fiberglass (ArmorCore, see www.armorcore.com), carbon fibers,and other carbon structures, boron treated cloth, etc. and combinationsthereof. Ballistic cloths can be used for such panels, such as bylaminating such cloths, with or without other materials.

The blinds can be made with slats in more than one thickness. Forexample, two different thicknesses including ¼ inch or ½ inch thickslats may be provided. The blinds might have slats with a width of 3inches, among other widths, as desired. The blinds can overlap (e.g.,when closed) more for additional support and protection, and may includestructure to enhance structural strength. Different types of cord forthe panels to hang from, including exotic fibers such as boron andcomposite fiber, can be utilized. The blinds could fasten at the bottomor sides for additional strength and stability.

As examples, slats made from ArmorCore can be provided of dimensions2″×36″×0.35″ (weight=1.9 lbs./slat) Slats made from Tensylon can beprovided of dimensions 2″×36″×0.23″ (Total weight=0.6 lbs./slat).

Shades can be provided that are of a uniform material that don't useslats, but instead use one or more uniform layers of ballistic material,which may or may not be laminated, and may even be formed into panels orslats. Such shades can drop automatically, as described herein for theblinds. The shades may be opaque (blackout shades), or somewhattransparent (translucent) or totally transparent, or otherwise havesmall or large gaps to let light through, as desired. Multiple layers ofmaterial can be used in the shades, and the shades may be used incombination with the blinds to add extra protection. For example, theshade may automatically deploy (drop) when a ballistic event isdetected, while blinds may automatically close (such as by rotating theslats).

FIG. 9 shows an example anti-ballistic window blind 600 that isautomatically deployable. The blind has a valance 620 for housing anynecessary gearing or other transmission mechanisms to allow the motor630 to deploy and retract the blind 610. The valance 620 may bedecorative in nature to be pleasing aesthetically, or covered in adecorative cloth or covering. Controller 640 may be wirelessly capableto communicate with an external control unit 690, or a home defensesystem (such as an anti-burglar system) by wire or wirelessly. A panicbutton 642 might also be provided to quickly deploy the blind. Theindividual slats 611 are comprised of material to provide anti-ballisticprotection, as described in more detail above, and may have decorativelayers as well. Vibrator 650 may be provided to apply vibration to theblinds to hamper audio detection systems.

A weight bar 615 can be used to weigh the blind 610 to aid indeployment, if desired. If desired, this weight 615 can be made of amagnetic material to be held in place by a magnet or electromagnet 617provided on a window sill or floor or wall, such that the electromagnetis activated when a security situation is detected or otherwisetriggered to better secure the blind 610 in place and improve itsanti-ballistic performance. For power outages, the electromagnet may bebattery powered, and only activated during as security event.Alternatively, a mechanical or electrical latch could be used for thispurpose.

Alternatively, rather than a motor, the drive system 630 may utilizeelectromagnets or solenoids or pneumatic or hydraulic devices to retractand/or release the blind. For example, electromagnets may be used tohold the blind in a retracted position, for deployment during a securityevent by powering down the electromagnet when deactivated either byautomated or manual means (as described herein), or by power outage, inwhich case the blinds, which can be weighted, can automatically deploy.

FIG. 9A shows a side view of an interlocking blind system where theslats 690 have grooves 694 and matching tongues 692 that allow adjacentslats to interlock with each other to add additional strength to theoverall blind. Alternative structures could be used for similarpurposes, such as tabs and slots, or curved edges, or evenelectromagnets.

FIG. 4 shows a similar deployable blind 610 that might be deployed in avehicle, such as a truck, automobile, train, aircraft, or other vehicleto protect vehicle access points like windows.

In contrast, a fixed barrier might be deployed within the door bodypanels, or other hollow body locations, that is permanently deployedwithin the door and attached to the door frame to add anti-ballisticproperties to the body of the door. Such a barrier might have the upperportion attached to the door frame but hang freely within the doorpanels within free space in the door to provide the benefits of such astructure as described herein. The barrier would then absorb the energyof a projectile as described above. Such a barrier could be installedduring manufacture of the vehicle, or might be provided as anafter-market installation to add anti-ballistic properties to existingvehicles. The window blinds might also be added at the factory or as anafter-market add-on.

For example, the flexible barrier in, say, a 3.5 inch door cavity takesup about ¼ inch to 1 inch of the overall space. The shock wave that goesacross the material from the projectile dissipates the energy throughand across the whole piece of material rather than just a small areadirectly around the projectile when the material is affixed to thestrike face of the door. The shock wave dissipates the energy moreefficiently through the material than would a fixed barrier.

Other options for use in vehicle door panels and other hollow bodiesinclude inflatable bags that can fill with an anti-ballistic gel, sand,balls or other material to provide anti-ballistic protection. Airbagtype devices might also be provided that deploy outside of the bodypanels to protect individuals inside the vehicle, where such airbagsmight be comprised of anti-ballistic inflatible sheets as discussedherein or filled with anti-ballistic material such as a gel. Suchsystems may be automatically or manually deployed, or permanentlydeployed, all of which is discussed herein and in the parentapplications for various barrier embodiments.

FIG. 11 shows a protection system 700 that uses a deployable airbag 720that is comprised of anti-ballistic materials, such as described herein.This airbag 720 can be provided between panes of glass 710, 712, forexample, and can be inflated using a pump or air tank 730 with a valve732 for sealing the air bag. When retracted, the deflated bag may residenear the top of the structure, perhaps hidden from view. A controlsystem 740 can be provided, such as to wirelessly connect to a homedefense control system or a remote control, for example. In some cases,the air bag may not be retracted, but may be permanently deployed. Notethat the bag might be filled with an anti-ballistic gel (as describedhereinbelow), rather than air, to add additional protection.

FIG. 12 shows a protection system 800 that uses deployable beads 820that are comprised of anti-ballistic materials, such as describedherein. This system can be provided to deploy bead between panes ofglass 810, 812, for example, and can be inflated using a bead storagetank 830 with a valve 832 for releasing the beads or pumping them inplace. A control system 840 can be provided, such as to wirelesslyconnect to a home defense control system or a remote control, forexample.

Note that for some applications, the beads may be deployed permanentlybetween the panes of glass, or anywhere else that ballistic protectionis desired, including in hard-to-reach areas such as in doors or walls.The beads may be small and light enough to be deployed by using a pumpor fan to blow the beads in place, and/or to remove them.

The beads can be comprised of any of the materials described herein,including ceramic materials or carbon fiber materials which may beparticularly applicable for this purpose.

The blinds or shades can be utilized in automotive applications, such ascurrently blinds that are provided in some vehicles, such as inlimousines or luxury vehicles, for example. FIG. 10 shows an examplestyle of blind that can be used in an automobile, which could beconstructed of ballistic material. The blind is shown in retracted mode610, and partially deployed mode 620. The bullet proof vehicle blindscan be provided on the inside of glass, mounted using mounting hardwarevalance 630 with bullet proof material sheet 640, or the blind couldreside between layers of safety glass (e.g., in automobiles) or eachlayer of glass can have a layer of safety film on them such as, forexample, 4-10 mil.

FIG. 13 shows an example blind 650 that could be used in a vehicle, suchas an automobile or even an aircraft. The window 652 is fitted with anantiballistic blind 655 that is deployed from valence 657 that ismounted in the window, or might be mounted in a roof of the vehicle. Aweight bar 659 might be provided to ensure that the blind properlydeploys, such as by gravity. Such blinds would more likely not bevenetian style, but instead be solid sheets of material, as discussedherein, that drop manually or automatically upon detection of anemergency condition.

Note that anti-ballistic sheets might be used to provide protection indoor and other body panels or other cavities. Alternatively oradditionally, air bags constructed of anti-ballistic material (seediscussion below regarding FIG. 11 for some examples), could beutilized. For example, the airbags of a vehicle might be constructed ofanti-ballistic laminates as disclosed herein, or filled withanti-ballistic fibers or gels or other materials. Alternatively,additional anti-ballistic air bags could be provided in the vehicles.

The blind could be deployed in a manner similar to that discussed abovewith respect to other blinds, and these vehicle blinds might also haveadjustable blades/louvers, which can have a groove that runs the lengthof the louver. This groove or notch can allow the louvers to interlockfor additional strength. With either the home/commercial application orthe automotive application the blinds can be electronic and closeautomatically when gunfire is sensed. The front windshield one couldclose partially or slowly according to the speed of the vehicle. Theblinds could have fasteners that allow them to interlock. The blindscould also engage with the window sill for added strength. There couldalso be 2 or more layers of blinds depending on the threat. This wouldalso allow light in but keep bullets out.

Such blinds may be deployed in school buses, public transportation(busses, trains, trolleys, taxis, even planes, for example) to protectchildren or other members of the public in battlefield areas or indangerous cities or sections of cities, for example. Schools and otherpublic buildings could be provided with such blinds, for example.

The blinds could be used to retrofit existing vehicle blinds that do nothave bullet-proof or other ballistic features, or they could beinstalled as original equipment or as after-market add-ons.

The vehicle blinds could be configured to vibrate at a random orconstant rate, as described above, to prevent an interferometers orvibration sensing listening devices from working through the blinds,avoiding eavesdropping or other spying activities. Vibration can beapplied to the blinds through use of motors or piezo devices in a mannerknown in the art to create vibrations. Such blinds may be ideal forboard rooms or military planning rooms to avoid spying operations.

Note that blinds that are constructed of ceramic or composite ballisticmaterial can be much lighter and cheaper to build than blinds that usemetallic materials, such as steel, for example, and they could proveflexible and more deployable and retractable.

Blinds using fabric and/or panels held together by fabric can beutilized. Also having blinds in a horizontal or vertical position.Closing and opening from all possible sides can be provided, e.g., fromthe top or bottom or left or right. Also a combination of theseapproaches can be used. Blinds could close from both sides. Or closefrom the top and bottom where each blind half covers half of aparticular window.

Roll down fabric blinds using ballistic materials that come down fromthe top, such as that can be quickly deployed can prove useful. Alsopanels that fold down from the top can be utilized.

Ballistic resistant panels can be provided with the ballistic materialprovided on back of an ornamental design (e.g., wooden slats), orbetween ornamental designs, so that the blinds provide traditionalornamental aesthetics. The ballistic materials may be woven into alayered cloth that can be attached, glued, or otherwise combined withthe ornamental panels to achieve the desired effect. A string or ropemade of the ballistic material can be used to replace the string/ropethat may be utilized in existing blind applications.

For example, FIG. 7 shows a side view of a laminated slat 400 havingballistic layer 420 sandwiched between decorative layers 410 and 430. Asan example, layers 410, 430 could be a single layer of fabricsurrounding a ballistic panel as layer 420. Or ballistic layer 420 mightcomprise a ballistic fabric, making the entire slat of layers of fabricand/or sheets of material. Hence, part of the blind, such aslouvers/slats, can be made in this laminated manner to provide bothdecorative and anti-ballistic features. The layers could be gluedtogether, or bonded in some other manner, such as by heating them toweld them together or stitching them together using a strong thread, asdescribed for the embodiment shown in FIG. 7A, discussed below. Alamination machine that binds the layers using heat can be used.

FIG. 7A shows an example blind comprised of an anti-ballistic laminate450 having a plurality of layers of flexible, anti-ballistic material455 and a decorative top layer 452 that are stitched together usingstitching 458. An embodiment may use any number of layers ofanti-ballistic material, which may be a woven cloth material or a thinsheet. For example, such a blind might use two, or more than two suchlayers. In a preferred embodiment, 18 layers of level 3A bullet proofmaterial, such as an antiballistic cloth material or thin sheets ofmaterial as discussed above can be stacked into a laminate that can beglued, heat welded, or stitched using a thread, such as nylon,polyester, Kevlar or Dyneema® threads, to secure the layers together.The top (and in some cases bottom as well) decorative layer 452 can becomprised of a decorative cloth or sheet. A binding material or stripcan be put around the outer edge of the sheets or slats for decorativepurposes or for physical support and further binding. For large sheetsof materials, stitching will be provided at periodic intervals (e.g.,0.75 inch spacing).

For example, 18 plies of woven Kevlar fabric such as a 600d Kevlar KM2Plus, 24×24 square yarns per inch, plain weave construction, polyesterstitching yarn, 75 denier textured yarn with a stitch pattern from alinear chain stitch (machine direction), 3.5 gage spacing or 0.75 inchspacing.

Sheets of material of the blinds, or individual slats, may have theindividual fabric sheets bound by using a glue or substance around aperimeter of the sheets or a pair of edges to hold the sheets together,but let the layers remain unbound in an interior portion. FIG. 7B showsa side view of an example two-layer laminate 200 with first and secondfabric layer 201 having only upper and lower edges 202 bound with anedging material (such as stitching, bonding, edging, etc.) leaving aninner gap 205 formed from the loose material. Of course, any number oflayers can be used in the laminate rather than just 2. This approachcould be designed to self-destruct in order to better absorb the energyof a projectile.

The laminated material of FIG. 7 or 7A or 7B can be formed into slats toform venetian style blinds, or alternatively into sheets to form solidblinds that can be used in homes or vehicles as discussed herein.

Alternatively, tensylon slats can be used for the venetian style blinds.As an alternative, a thin layer of steel as a strike face can beprovided on the slats to improve the anti-ballistic properties. Tensylonslats, with or without the steel surface layer, can slide in pockets onthe kevlar fabric blinds to add further protection, such as in solidsheets that are rolled up when retracted and unrolled when deployed, asdescribed hereinabove. Such blinds re flexible and lightweight, andcould be designed to level 4 protection to stop rifle rounds.

For vertical blinds such as shown in FIG. 1A, the blind panels from asupport structure, and they can be pulled to a side horizontally to openthe blinds. The slats may also be rotated to open the blind to light, orto block the light or provide privacy, such as at night. Such a systemmay be automatically deployed (i.e., closed) by both extending theblind, and/or rotating the slats closed, depending on the current stateof deployment, to provide ballistic protection when a threatening eventis detected, as discussed above.

Ballistic blinds might also be arranged in a manner similar to drapes,where ballistic fabric is used to form the bullet proof drapes. In thiscase, the drapes can be deployed in a manner similar to fabric drapes.Vertical slats can be used in such approaches as well, where the slatsfold together when the “drapes” are withdrawn (opened), and unfold whenthe “drapes” are deployed (closed).

Note that blinds could also be installed in the interior of rooms oragainst walls with the structures being installed at the ceiling orabove a drop ceiling, so that the blinds can be dropped when needed forprotecting a wall or room. Automatic deployment can occur as discussedabove for window blinds. It has been found that free-hanging blinds canactually perform better than blinds that are secured at the bottom orsides, likely due to better energy dissipation properties when the blindis permitted to move upon impact with a bullet or shrapnel. Hence,blinds without being secured at the bottom and sides are of particularinterest and make up some preferred embodiments, although a weight maybe used on the bottom edge of the blinds to aid in deployment.

An alternative blind design could utilize thin layers of glass withgraphene centers or Lexan between two layers of glass that may betransparent or translucent sheets or slats. A transparent or translucentanti-ballistic gel might also be used, such as shear thickening fluidsthat are transparent to fill the gaps between window panes or layers ofglass. Some of these materials harden upon impact and might be comprisedof non-Newtonian fluids that that thicken in response to force (such asmixtures of cornstarch and water do). Examples of such materials havebeen disclosed recently but their composition are trade secrets.

It is desirable that the blinds meet NIJ level IIIA standards or above.Large sheets of material can be formed which are then water jet cut to2.5″×36″ strips of material out of the larger sheets for slats, forexample.

Many other example embodiments can be provided through variouscombinations of the above described features.
